LTC1421IG#TRPBF

Hot Swap Controllers Overview

The LTC1421IG#TRPBF is a Hot Swap Controller manufactured by Analog Devices Inc., designed to allow safe board insertion and removal from live backplane systems. It utilizes external N-channel pass transistors to ramp up supply voltages at a programmable rate, protecting against inrush current and short circuits. The device features a programmable electronic circuit breaker, system reset control, and power good outputs. It supports supply voltages ranging from 3V to 12V and includes connection inputs to detect board presence.

Hot Swap Controllers Feature Summary

• Enables safe hot swapping of boards into live backplanes using external N-channel pass transistors for controlled voltage ramping.
• Integrates a programmable electronic circuit breaker to protect against overcurrent and short-circuit conditions during insertion or fault events.
• Provides dedicated System Reset and Power Good control outputs to manage downstream logic states and indicate stable power delivery.

Hot Swap Controllers Applications

• Server and storage backplane systems requiring safe module insertion
• Industrial control boards with live bus requirements
• Telecommunications equipment modules needing controlled power-up sequences

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation, as historical data may vary. Ensure the design accommodates the required external N-channel MOSFETs and programming components for threshold and ramp settings. Cross-reference the datasheet revision date to confirm pinout and electrical characteristics match the intended application requirements.

Hot Swap Controllers Selection Notes

Select this component when designing systems that require controlled power sequencing for hot-swappable modules. It is suitable for applications supporting supply rails between 3V and 12V. Designers must account for external pass transistor selection and thermal management. Verify that the required protection thresholds and ramp rates align with the system's backplane specifications and load characteristics.
